  • Publication number: 20130309890
    Abstract: A connector holding structure includes a pair of holders each shaped substantially like a U and having a base and a pair of arms extending from both ends of the base; and levers. The pair of arms includes a connector support portion in which the distance between their inner side surfaces is narrower at positions adjacent to the base than the width of the connector opening, and notched portions for getting rid of interference with the claw tabs. The holders are placed respectively at both ends along a longitudinal direction of the connector opening and housed in the faceplate. The lever causes the faceplate to support the holder in one of a position for a holder locked state and a position for a holder released state.

  • Patent number: 7999652
    Abstract: In a flat plate type thick film resistor, an insulation performance is improved by excluding the nonuniformity of potential distribution on a wiring plane, which is generated when electric current flows in a resistance wire. Simultaneously, generation of noise depending on potential distribution and variation of stray capacitance around a resistor is suppressed. When the resistance wire having a constant thickness and uniform resistivity, which is formed on an insulating substrate, is connected to a pair electrode conductors that face to each other, in the way that the resistance wire is repetitively bent to the alternate side in zigzags, a potential gradient on the wiring plane, which is generated when electric current flows in the resistance wire, is constant by properly selecting the line width, the bending angle, and the spacing between bending vertexes of a resistance wire.
